Perhaps you should try some spelling variations:
juan rene » juan meng, juan rana
hua rene » hua ren
ying jin » yang jin, jing ji, yang jie
jin wong » jin song, john wong, jin ying
wong sau » wong sam, wong siu, wong shiu
yan yan » yan yuan, yang yang, wang yan
nan yan » nan ya, wang yan, qian yan

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: wan ((yan yan) OR (nan yan)) ((hua rene) OR (juan rene)) ying jin wong sau ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wan ((yan yan) or (nan yan)) ((hua rene) OR (juan rene)) ying jin wong sau ;~".
• Adding a wildcard symbol may retrieve word variants: wan ((yan yan) or (nan yan)) ((hua rene) OR (juan rene)) ying jin wong sau ;*.
